Abstract: Objective: To evaluate the clinical application value of suture the lower uterine segment for placenta previa cesarean section hemorrhage. Methods: Forty cases of intraoperative hemorrhage with placenta previa were to meet the study selected in our department from September 2012 to May 2014. All cases were randomly divided into two groups: 20 cases were chosen as the observation group for suture the lower uterine segment. Twenty cases were chosen as the control group for ascending branch of uterine artery ligation. Blood loss, surgical duration, postoperative duration of hospital, puerperal infection, hysterectomy rates were compared. Results: ①There were difference about blood loss volume and volume of blood transfusion in two groups (P<0.05). No ststistical difference was found between the groups in transfusion rate (P>0.05). ②There was difference about surgical duration in two groups (P<0.05). ③There was significant differences about postoperative duration of hospital in two groups (P<0.01). ④Three cases with postpartum hemorrhage of refractoriness were performed subtotal hysterectomy in the control group. Both of the two group did not appear the puerperal infection and maternal death. At the postpartum follow-up, all women described normal lochia and involution of uterus was found in pelvic examination. All women referred resumption of normal periods. No complained of painful in the pelvis. Conclusion: The method of suture of the lower uterine segment is effective technique for treating cesarean section hemorrhage of placenta previa. It has the benefits of the easy operation, rapidly mastering, quick hemostatic, low transfusion, reducing postoperative duration of hospital stay and the preservation of uterus. It is worthy of clinical promotion.
